Surprising that a garage couldn't tell it was a 6" rim. R6 only has a 5.5" rear so it would be off something else, I put a 6" R1 rear on mine so I could use a 190, perhaps someone has done the same to yours. I run 190/55's and they are perfect. The wheels are not a straight swap so yeah there will have been mods to get it in.
If it is a 6" rear then you will need a 190 tyre on it really.
